我正在尝试构建一个计步器应用程序，作为测试我从github下载了android fit代码并运行了basicsensorsAPI：
为了获得stepcount而不是location，我将数据类型更改为 TYPE_STEP_COUNT_CUMULATIVE和TYPE_DERIVED ，（orignials为 TYPE_LOCATION_SAMPLE和TYPE_RAW ）。但是一旦我这样做，OAUTH就会停止工作，我不确定为什么会造成这个问题。
以下是更改后的代码：
private void findFitnessDataSources() {
// [START find_data_sources]
// Note: Fitness.SensorsApi.findDataSources() requires the ACCESS_FINE_LOCATION permission.
Fitness.SensorsApi.findDataSources(mClient, new DataSourcesRequest.Builder()
// At least one datatype must be specified.
.setDataTypes(DataType.TYPE_STEP_COUNT_CUMULATIVE)
// Can specify whether data type is raw or derived.
.setDataSourceTypes(DataSource.TYPE_DERIVED)
.build())
.setResultCallback(new ResultCallback<DataSourcesResult>() {
@Override
public void onResult(DataSourcesResult dataSourcesResult) {
Log.i(TAG, "Result: " + dataSourcesResult.getStatus().toString());
for (DataSource dataSource : dataSourcesResult.getDataSources()) {
Log.i(TAG, "Data source found: " + dataSource.toString());
Log.i(TAG, "Data Source type: " + dataSource.getDataType().getName());
//Let's register a listener to receive Activity data!
if (dataSource.getDataType().equals(DataType.TYPE_STEP_COUNT_CUMULATIVE)
&& mListener == null) {
Log.i(TAG, "Data source for LOCATION_SAMPLE found! Registering.");
registerFitnessDataListener(dataSource,
DataType.TYPE_STEP_COUNT_CUMULATIVE);
}
}
}
});
// [END find_data_sources]
}
这是原始代码：
private void findFitnessDataSources() {
// [START find_data_sources]
// Note: Fitness.SensorsApi.findDataSources() requires the ACCESS_FINE_LOCATION permission.
Fitness.SensorsApi.findDataSources(mClient, new DataSourcesRequest.Builder()
// At least one datatype must be specified.
.setDataTypes(DataType.TYPE_LOCATION_SAMPLE)
// Can specify whether data type is raw or derived.
.setDataSourceTypes(DataSource.TYPE_RAW)
.build())
.setResultCallback(new ResultCallback<DataSourcesResult>() {
@Override
public void onResult(DataSourcesResult dataSourcesResult) {
Log.i(TAG, "Result: " + dataSourcesResult.getStatus().toString());
for (DataSource dataSource : dataSourcesResult.getDataSources()) {
Log.i(TAG, "Data source found: " + dataSource.toString());
Log.i(TAG, "Data Source type: " + dataSource.getDataType().getName());
//Let's register a listener to receive Activity data!
if (dataSource.getDataType().equals(DataType.TYPE_LOCATION_SAMPLE)
&& mListener == null) {
Log.i(TAG, "Data source for LOCATION_SAMPLE found! Registering.");
registerFitnessDataListener(dataSource,
DataType.TYPE_LOCATION_SAMPLE);
}
}
}
});
// [END find_data_sources]
}
我得到了这个输出：应用程序需要得到用户的oAuth同意。

我也遇到过这个问题
如果您遇到此问题，则需要获得权限：只需在onResult()方法
if (dataSourcesResult.getStatus().getStatusCode()==5000)
{
try {
dataSourcesResult.getStatus().startResolutionForResult(SplashActivity.this,10);
} catch (IntentSender.SendIntentException e) {
e.printStackTrace();
}
}
并在onActivityResult中再次调用您的方法
if (requestCode==10 && resultCode==RESULT_OK)
{
findFitnessDataSources();
}

第3步：获取OAuth 2.0客户端ID
如果您尚未启用Fitness API并获得OAuth 2.0客户端ID，请按照获取OAuth 2.0客户端ID中的说明立即执行此操作。
此外，
在您的应用可以读取或写入健身数据之前，始终需要用户同意。获得授权：
- 使用Google Developers Console中的项目注册您的Android应用。
- 指定连接健身服务时的访问范围。
在Google健身中，范围是字符串，用于确定应用可以访问哪种健身数据以及对此数据的访问级别。
授权流程如下：
- 您的应用会向健身服务部门申请一个或多个访问范围的连接。
- Google Fit会提示用户授予您的应用所需的权限。
- 如果用户同意，您的应用可以访问范围定义的类型的健身数据。
用户请求的特定权限取决于您的应用在连接服务时指定的范围。
连接到Google健身平台，然后根据您在应用中使用的Fit API的要求检查并请求权限：
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
// Put application specific code here.
setContentView(R.layout.activity_main);
// This method sets up our custom logger, which will print all log messages to the device
// screen, as well as to adb logcat.
initializeLogging();
// When permissions are revoked the app is restarted so onCreate is sufficient to check for
// permissions core to the Activity's functionality.
if (!checkPermissions()) {
requestPermissions();
}
}
创建Google API客户端并提供所需的回调方法：
**
* Build a {@link GoogleApiClient} that will authenticate the user and allow the application
* to connect to Fitness APIs. The scopes included should match the scopes your app needs
* (see documentation for details). Authentication will occasionally fail intentionally,
* and in those cases, there will be a known resolution, which the OnConnectionFailedListener()
* can address. Examples of this include the user never having signed in before, or having
* multiple accounts on the device and needing to specify which account to use, etc.

private void buildFitnessClient() {
if (mClient == null && checkPermissions()) {
mClient = new GoogleApiClient.Builder(this)
.addApi(Fitness.SENSORS_API)
.addScope(new Scope(Scopes.FITNESS_LOCATION_READ))
.addConnectionCallbacks(
new GoogleApiClient.ConnectionCallbacks() {
@Override
public void onConnected(Bundle bundle) {
Log.i(TAG, "Connected!!!");
// Now you can make calls to the Fitness APIs.
findFitnessDataSources();
}
@Override
public void onConnectionSuspended(int i) {
// If your connection to the sensor gets lost at some point,
// you'll be able to determine the reason and react to it here.
if (i == ConnectionCallbacks.CAUSE_NETWORK_LOST) {
Log.i(TAG, "Connection lost. Cause: Network Lost.");
} else if (i
== ConnectionCallbacks.CAUSE_SERVICE_DISCONNECTED) {
Log.i(TAG,
"Connection lost. Reason: Service Disconnected");
}
}
}
)
.enableAutoManage(this, 0, new GoogleApiClient.OnConnectionFailedListener() {
@Override
public void onConnectionFailed(ConnectionResult result) {
Log.i(TAG, "Google Play services connection failed. Cause: " +
result.toString());
Snackbar.make(
MainActivity.this.findViewById(R.id.main_activity_view),
"Exception while connecting to Google Play services: " +
result.getErrorMessage(),
Snackbar.LENGTH_INDEFINITE).show();
}
})
.build();

关于范围。访问此google developer page
要添加数据的数据类型应在范围内。表示您是否要添加
DataType.TYPE_DISTANCE_CUMULATIVE
您需要添加相关范围。
.addScope(new Scope(Scopes.FITNESS_LOCATION_READ_WRITE))
如果你想添加
DataType.TYPE_STEP_COUNT_DELTA
比你需要添加范围
https://www.googleapis.com/auth/fitness.activity.write
或＆＃34; FITNESS_ACTIVITY_READ_WRITE＆＃34;
